Fiber lasers refers to rare earth doped laser glass fiber as the gain medium, fiber lasers developed on the basis of the optical fiber amplifier: the role of the pump light can easily form a high power density within the fiber laser engraving machine, resulting in laser laser level work of substance "inversion" Tobacco encoded laser engraving machine, when appropriate positive-feedback loop (constituting a resonant cavity) can form a laser oscillation output. Fiber lasers wide range of applications, including laser fiber-optic communications, laser space telematics, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing roll, metal and nonmetal drilling / cutting / welding (brazing , hardening, cladding and welding depth), military defense and security, medical equipment, large-scale infrastructure and so on. Laser-material interaction exists when a threshold power, only the laser power reaches this threshold, the physical process can begin. Laser marking threshold kW power in general order of magnitude. For highly reflective surfaces or difficult material for processing in terms of mobile phone accessories laser engraving machine, pulse peak power needed to reach the level of more than 10kW. But for most materials Sanitary Materials laser marking applications laser engraving machine, a few kilowatts of peak power to meet the needs. Another key parameter is the pulse energy, typically on the order mJ. Pulse length of time is a very important feature, because it determines the effect of heat and material time, have a significant impact on the quality of identity. Typically the length of time required between pulses 10 ~ 200ns. Pulse frequency is the number of pulses per second (in Hz), typical laser marking system operating frequency range of 20 ~ 80kHz. Average power is determined by the pulse energy and pulse frequency, average power value represents the total energy of the laser can provide.
